Planetary reducers borrow Kling motion control; the housing photo is the ratio

industrial-gearbox-oem already put ratio math on a Qwen slide. This leftover is carrier motion on the photographed sun/planet set. Kling V3 Pro motion control is audio false, 17cr, 1080p: transfer a known rotation; do not regenerate stage count. /for/robotics-companies is still not this catalog row.

A planetary listing that ships is the housing you already signed — ring, carrier, the planet set a buyer can pause on — then a few seconds of rotation you actually have on tape. It is not a second spec slide, and it is not an uncut robot cell. This page is leftover motion on this sun.

Ratio math already lives on a Qwen slide

Gearbox ratios belong on a Qwen slide, not inside the prompt is the industrial-gearbox job: ratio, service factor, mounting, lettered on a Qwen board at 4 credits, 2K. That board is the catalog math. This leftover is not a second board. Do not re-prompt the ratio into a video paragraph so the housing “shows 15:1 on the bell.” You will get cousin glyphs and a stage count the datasheet does not print.

If a campaign still needs the number on the clip, overlay the string you already approved. Do not ask motion control to typeset it. Silent transfer will not letter a ratio, and a prompted plate is a spec you cannot edit without regenerating the case.

Keep the jobs split. Slide: math. Housing photo: identity. Driving clip: rotation you would copy. Mixing them in one generate is how a 2-stage carrier finishes as a 3-stage cousin.

The housing photo is the carrier

Photograph the reducer you sell. Square to the sun. Planets in frame. Ring readable. Nameplate if the listing needs it. That still is the print. Text-to-video will invent a cousin housing with a different stage count and a cleaner paint job. The buyer is matching iron, not atmosphere.

Crop the bench. Hold the bolt circle. Do not prompt a cutaway the plant never sectioned. An open-case still is a different still, shot on your floor, not a sentence about “see the planets.” Wrong planet count is a different reduction. Wrong stage count is a different SKU.

Prompt camera and physics only once the still is locked. Carrier turns. Sun holds. Camera locked. No new stages. No new ports. If the still includes a serial, keep it. Do not prompt it off and hope the model rebuilds the ring.

Kling V3 Pro motion control transfers a known rotation

Kling Video V3 Pro Motion Control is the transfer row: a reference image plus a driving video, 1080p, 17 credits, audio false. The file is silent. Quoted ratio names in the prompt do not become a soundtrack and do not become nameplate glyphs.

The still is the character contract. The driving clip is the motion contract. You need both. Transfer a dance or motion onto my photo is the named agent job for this pair: photo in, driver in, retargeted motion out. Missing the driver is ordinary image-to-video. Missing the still is a generated machine.

The driver should be a rotation you would actually copy — carrier turning on a unit in the same family, readable, one housing in frame. A messy cell walkthrough with three reducers will transfer mess. Prompt the travel: hold identity, copy the carrier, camera locked, no new stages. Do not prompt “planetary gearbox spinning in a cinematic factory” as if language could specify tooth count.

Because audio is false, this clip is silent. Do not write a VO into the Kling prompt and wait for an applications engineer. Overlay the ratio after lock if it must appear. Do not regenerate stage count. If the still shows two stages, the clip may not finish as three. Those are claims. A buyer will notice them before they notice your logo.

Wan 2.7 is leftover orbit; robotics is a different plate

Wan 2.7 Image to Video is the leftover still-to-motion row when you do not have a driving clip: 2s–15s, 1080p, 15 credits, catalog audio unset, optional driving audio listed, three modes (first-frame, first-and-last, continuation). Treat it as orbit on the photographed housing, not as a transfer of a known rotation. Start at 2s–5s. Fifteen seconds of the wrong planet set is a long miss. Do not claim native voice on this slug. Do not use Wan to invent stage count you did not photograph.

First-last is only useful when both stills are the same reducer — closed housing and a section you actually cut. Two different ratios is a morph. Continuation is for a take you already approved, not a way to grow a third stage.

Robotics companies is still not this catalog row. That page is an uncut cell at real speed: integration, cycle time, failures visible, 16:9, two posts a week, YouTube and LinkedIn. A planetary OEM is a component. Do not rewrite the robotics page as a carrier orbit. Do not speed-ramp the housing unlabelled and call it a cell demo.

A constructed applications engineer walking “what you should spec for this arm” is a presenter you did not hire. Silent transfer. Overlay the ratio. If a human must speak, that human is on payroll and on a different take.

FAQ

Can I prompt Kling to “match this reducer” instead of uploading the housing photo?

No. A sentence is not a plate. Motion control needs a reference image and a driving clip. Upload the photographed sun/planet set. Describe only the rotation.

Why motion control instead of Wan 2.7 on the still?

Because the rotation already exists on tape. Wan 2.7 image-to-video invents motion from one photo (2–15s, 1080p, 15 credits). Motion control copies a driver onto an approved still, silent, 1080p, 17 credits. If you do not have a driver, you do not have the Kling job.

Does locking the housing mean I can regenerate a prettier stage count?

No. Stage count is the SKU. Two stages in the still must stay two. Overlay the ratio from the Qwen gearbox slide if the number must appear. Do not grow planets.

How is this different from /for/robotics-companies?

Robotics companies is the uncut cell, integration, and a sceptical technical buyer. Planetary OEM is the housing photo and transferred carrier motion. Different plate. Different page. Do not merge them in one generate.
